How do I transfer my buyers' payment funds into my bank account?

E-junkie does not handle any actual payment funds at any point during the purchase process. Your checkouts with E-junkie would be handled by an independent payment service such as PayPal, Stripe, Authorize.Net, etc.. To transfer payment funds into your bank account, you will need to consult the help pages or support staff for your payment service(s) to get their instructions on how to accomplish that in their system.
